thanks for pointing out my error
Its at 11 bars
Cheers
Those snow tires make a big difference on range. I will also note that when the capacity of the LEAF battery drops, it affects the top portion of the SOC range much more than the bottom portion. in other words, your car likely has lost more range from 100% SOC down to 76% SOC than from there down to zero. Also, this effect seems to get worse just before losing a bar which is where your LEAF appears to be.MVLeaf wrote:In a warmish spell of weather, mid-40Fs, I'm seeing drop from 100% charge to 76% after 15 miles. I should say I have new snow tires all around mounted on steel wheels.
Possibly both are "correct". The first one is how much capacity the BMS thinks the battery has at 100% charge. The lower number is how much is available at the current SOC. But the BMS has plenty of room for error, so neither is fully accurate.MVLeaf wrote:Which Ahr value is correct?
It's hard to know if they did anything tricky, such as resetting the BMS to indicate 12 bars remaining, even though one or more capacity bars has previously been lost. IMO, 54.12 Ah is low enough that you *should* have lost the 12th capacity bar. It also doesn't seem to match the SOH of 87.15% (which I would expect to be lower).MVLeaf wrote:I'm trying to determine if the dealer did anything tricky or if just perhaps didn't treat it well during the couple of years they had it on the lot with little usage.
No.MVLeaf wrote:From this point forward, is there any reason to think that this car will lose bars faster than others over the next, say, 50,000 miles?
I used to, but I don't anymore. There are two reasons:MVLeaf wrote:Also, is it OK to leave the OBDII gizmo plugged in?
The table page shows estimated ahr remaining while the other two pages show estimated nominal capacity of battery pack. You should always go by the latter since the former is COMPLETELY dependent on the SOC.MVLeaf wrote:First of all, please tell me if I am posting in the wrong place
On Nov 24th 2017 we bought a used 2015 SV from a dealer here in MA that had been used as a loaner vehicle to their customers, with 720 miles on the odometer and all 12 bars. Now has 2072 miles on the odometer, still 12 bars. In a warmish spell of weather, mid-40Fs, I'm seeing drop from 100% charge to 76% after 15 miles. I should say I have new snow tires all around mounted on steel wheels. But it's pretty flat here on Martha's Vineyard and no place where we drive above 45 mph.
I just got Leafspy Pro and I am seeing at the top of the Battery Cells graph a series of stats as follows:
54.12 Ahr SOH 87.15% Hx 78.8%.
On the Table page it has:
95.3% SOC 248 GIDs 51.58 Ahr 19.2 kWh.
Which Ahr value is correct?
I'm trying to determine if the dealer did anything tricky or if just perhaps didn't treat it well during the couple of years they had it on the lot with little usage. From what I read in other threads, this car is close to losing the first bar. MA has a lemon law which is 90 days so I'm about a week away from making any kind of claim if there is a basis for one.
Thanks very much, experienced insights would be most welcome.
I don't see anything that would make me think the dealer was underhanded, and certainly nothing that would put the car in the lemon class.MVLeaf wrote: I'm trying to determine if the dealer did anything tricky or if just perhaps didn't treat it well during the couple of years they had it on the lot with little usage.
